This problem can be caused by a power window and door lock switch. Especially the one in the driver's door.

For example, on my 3500 crew cab, when the window switch was damaged, the door locks acted up, it gave messages that a door was open, the dome light functions when the doors opened and closed were all screwed up, and the retained accessory power function was not working.

It seems damned near every door related function goes through the door lock and window switches. On my crew cab, for example, everything except the door speaker works through the master power window/power door lock/power mirror switch, including the driver's door switch and the seat heater.
